AD-BZX84B5V1 from Changjing, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A | passive | Anode of the zener diode, shown on the page 1 symbol as the arrow side of the diode connected to pin 1. |
| 2 | NC | unconnected | Not connected; the page 1 symbol shows pin 2 with no connection to the diode. |
| 3 | K | passive | Cathode of the zener diode, with a nominal zener voltage of 5.1 V (5.00 V to 5.20 V at IZT = 5 mA) for the 5V1 type. |
